Joanna Lumley Patsy 39 episodes, 1992-2012

Julia Sawalha Saffron 39 episodes, 1992-2012

June Whitfield Mother 36 episodes, 1992-2012

Jane Horrocks Bubble 32 episodes, 1992-2012

Edina's self-indulgent, substance abusing behaviour is contrasted by and frequently comes into conflict with her sensible, practical, Generation X daughter Saffron.

Edina's ruthless, parasitic fashionista best friend Patsy, who vies with Saffron for Edina's attention and leads and encourages Edina in her outrageously irresponsible behaviour.

The core cast also includes Edina's indifferent and emotionally distant Mother who delights in pointing out her flaws, stealing from her and enjoying her luxurious lifestyle. Also present is Edina's supremely incompetent secretary and personal assistant Bubble - who often seems confused by simple concepts and is disrespectful of her employer. She is kept on for the aesthetic merit of her bizarre outfits and because the work-shy Edina looks competent and efficient by comparison.
